Mr. Hamilton surveyed his class to find the total number of hours each of his students slept the previous night. The histogram shows the results of the survey.

How many students slept at least 8 hours?

Answer:

8|6

32|24

16|12

4|3

400|300

56|42

Step-by-step explanation:

Hey i'm Nate

So for this you want to use order of operations AKA (PEMDAS)

P: Parenthesis

E: Exponents

M: Multiplication

D: Division

A: Addition

S: Subtraction

You want to work in that order however Multiplication and Division can be alternated likewise with Addition and Subtraction. So for this question you would take the problem which is 4__ 6 -2 x4 +511 = 527  and then you plug in the signs to see which one works. The answer would be X because you would take -2x4 which is -8 then you would take 6x4 which is 24 then you subtract -8 and 24 and you get 16 then you take 16 and add 511 and then you get 527.

Answer:

11.25, the length is 11.25

Step-by-step explanation:

The dimensions are 4 2/3, 6 2/3 and ? if you multiply them, they equal 350

let ? = x

4 2/3 * 6 2/3 * x = 350

Multiply 4 2/3 and 6 2/3

31 1/9 * x = 350

divide both sides by 31 and 1/9

x = 11.25

He can make 29/28 bags after mixing 2/7 cup of trail into cup size bags.

The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the data in the question,

Chase put 2/7 cup into 3/4 of a cup size bag, then,

Total bags he can make = 2/7 + 3/4 = 29/28

Therefore, total bags made by him is 29/28.

Answer:

The circular pie

Step-by-step explanation:

The formula for the area of a circle is A=πr^2

Plugging in the radius gives us

A= π 7^2 then,

A= π 49

A= 153.94

Now the formula for the area of a square is A= a^2

Plugging the side length gives us

A = 12^2

A = 144

So 153.94 >  144

And done!

The number of problems Ryan can complete in 2 hours is 36.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Ryan can complete 3 math problems in 10 minutes.

Number of problems solved in 1 minute is 3/10

We know that, 2 hours =2×60

= 120 minutes

Now, the number of questions completed in 120 minutes are

3/10 ×120

= 36 problems

Therefore, the number of problems Ryan can complete in 2 hours is 36.

Step-by-step explanation:

I got A I hope this helps

Answer:

a. The given value is not a solution of the equation.

b. The given value is a solution of the equation.

c. The given value is a solution of the equation.

Step-by-step explanation:

a. 23 = x; x = 14 -> 23 = 14

This given value is not a solution to this equation because 23 doesn't equal 14.

b. n/13 = 4; n = 52.

Since, n = 52, replace n with 52 in n/13 = 4.

52/13 = 4 This given value is a solution to this equation.

c. 17y=85; y = 5

Since, y = 5, replace y with 5 in 17y=85.

17(5)=85 This given value is a solution to this equation.

64° + 76° + (2x+14)° = 180° (angle sum of triangle)

140° + 2x+14° = 180°

2x=180 ° - 14 ° -140°

2x=26°

x=13°

Answer:

x = 13

Step-by-step explanation:

the sum of the triangle angles always adds up to 180 degrees, otherwise it is not a triangle.

 64 + 76 = 140

180 - 140 = 40.

therefore, the last angle must equal 40 degrees.

2 * x + 14 is the equation we need to us to get to 40 degrees.

40 - 14 = 26

26 / 2 = 13

therefore, x equals 13

now, is we want to check our answer to make sure it is correct,

2 * 13 + 14 = 26 + 14

   26 + 14 = 40

  76 + 64 = 140

180 - 140 = 40

therefore, it works.

good luck my friend!

Answer:

x = 8

Step-by-step explanation:

In a triangle, the sum of the interior angles is 180 degrees.

So, for this triangle 180 = 100 + 48 + (5x - 8)

Now let's simplify this down to isolate x. Start by adding 100 and 48.

180 = 148 + (5x - 8)

Now subtract 148 from both sides.

32 = 5x - 8

Add 8 to both sides.

40 = 5x

Divide both sides by 5.

x = 8

8
